Fernando Ballesteros discusses the discovery of phosphine on Venus and other historical hypotheses regarding signs of life on other planets.
Through several maps, the text shows COVID-19's cartography and analyses the environmental factors that may have contributed to its spread.
Miracle diets can produce health issues due to rapid weight loss, excessive energy restrictions, and the exclusion of certain foods or nutrients from the diet.
Foods that are rich in fats and sugars are pleasurable because they stimulate our reward circuits, the same circuits that are activated by drugs. In a context in which unhealthy diets and drug abuse are common from adolescence, it is important to investigate their consequences.
For guidelines to be useful, they must consider cultural, anthropological, educational, social, and economic factors, as well as the usual diet of the target society.
There is a widespread misconception, mainly due to perverse agnogenic practices, that nutrition is hard and confusing, that we do not really know what to eat and that health professionals cannot agree.
Nutritional epidemiology currently studies the diet-disease relationships. In this review, we analyse the impact of diet on health and the importance of dietary factors in the prevention of non-communicable diseases.
Can the application of neuroscience to education be studied while maintaining every aspect of the scientific method used in neuroscience? Or, even more simply, can neuroscience be applied to education?
This is undoubtedly an encouraging stage for evolutionary biology. Palaeoproteomics has the potential to explore time intervals that were completely inaccessible until now.
The norm of our time is to eat alone and constantly consume individually-packaged, unidentified products.
Although humans' irresponsible and indiscriminate use of the natural environment could be one of the causes behind the recent coronavirus crisis, bats have been targeted for their role as natural reservoirs of zoonotic pathogens.
The word science has never been as present in the media as it was during the COVID-19 pandemic, and if this continues to be the case in the coming months, it is very likely that something will remain even after the coronavirus disappears.
Can an extraterrestrial organism produce a catastrophic pandemic on our planet? Such a question arises every time we consider bringing samples from other worlds in the Solar System, especially now, amidst the COVID-19 pandemic.
Using simple materials like plastic bottles, straws, modelling clay, and syringes you can witness many interesting phenomena relating to air and water pressure.
An epidemic like the one we have unfortunately experienced can bring out people's worst fears. Cinema and literature have successfully used fear to write scripts in which an epidemic is the heart of the story or the underlying excuse.
This section of Mètode is now twenty years old. To celebrate it, I retrieve a topic I talked about in issue 34: planetary nebulae.
Those of us who are dedicated to the creation and dissemination of knowledge must make intelligent use of its contingent and provisional nature, to promote the idea that what may appear to be weaknesses are, in fact, the features that allow scientific knowledge to progress and be disruptive.
Embracing an evolutionary perspective thus helps to explain why men and women react differently to certain infectious diseases and to understand (and combat) the strategies of viruses in their relentless evolutionary race to infect and spread among us.
Growing concern for health has fuelled interest in the relationship between diet and disease prevention. But despite the remarkable scientific advances, there are still many unanswered questions, and many evidence-based messages do not reach the population and are lost in a sea of misinformation and half-truths.
The concept of educating city is based on the evidence that space is not neutral, but rather generates, disseminates, and reinforces images and values in an explicit and implicit way. This communicative character is more intense the more complex, diverse, and richer the reference space is.
In the West, our idea of animated cinema is very much influenced by the work of Walt Disney. In Japan, the animated film tradition (anime) is very different. Complicated plots that are often not clearly targeted at a child or adult audience and ambiguous characters. Eastern animated cinema can even dare to make a film speculating on the philosophy of science.
We seem to be living a sweet moment for manned exploration missions to Mars. There are several projects underway, both by private companies and space agencies, which aim to be the first to put a human being on Mars. Does this mean that we are now going to make the ancient dream of stepping on Mars come true?
Maurice Hilleman is probably the scientist who has prevented the highest number of deaths and illnesses from infection in the history of medicine. He and his team obtained or improved more than 25 vaccines against viruses and bacteria.
What do you feel when you thnk about science? There are people who feel nothing at all and so they prefer other readings. I imagine that you will have many different ones, but which is the most prevalent, the one that weighs most heavily?
